“…Another option is to use the experimental data directly (as in e.g., [35,36]) 4 , which will further increase the deviation between the various predictions from AlterBBN. At this point we do not want to advocate one choice over another, but simply want to emphasise that the choice of rates matters, and unless the specific choice is discussed in the context of each result (which is usually not the case (e.g., [8,11,25])), this deviation between rates should be included as a systematic uncertainty. Better experimental determination of the rates at BBN energies will solve the issue.…”
